I also find that in a lot of movies the dialog is mixed too low and I need to bump the center channel a few dB. If it still bothers him, dynamic compression might be what he's looking for, worth to give it a try. Checking that all drivers are working is also a good idea. Try playing with the crossover setting, I like mine crossed at 60 and even 40Hz. And yes, BEAUTIFUL room!
